Install command & repo URL typos in README / SKILL.md

[leekeithlee]

What I found

While setting up self-improving-agent for OpenClaw, two copy-paste hazards
showed up in the README and SKILL.md:

1. Repo URL typo (peterskoett → pskoett)

   • README and SKILL.md reference github.com/peterskoett/self-improving-agent
     and git clone https://github.com/peterskoett/self-improving-agent.git.
   • That owner handle redirects to pskoett/self-improving-agent on the web,
     so git clone from a fresh machine fails until the user notices.
   • Affects: README.md, self-improving-agent/SKILL.md (Installation section),
     and self-improving-agent/CHANGELOG.md.

2. clawdhub install self-improving-agent command

   • README and SKILL.md (and CHANGELOG) advertise clawdhub install ... as
     the recommended install path.
   • clawdhub is not on the install path here; the working commands are
     openclaw skills install self-improving-agent (built-in) or
     clawhub install self-improving-agent (separate publisher CLI).
   • Right now clawdhub is the only install command that does not work
     out of the box.

Suggested fix

• Replace peterskoett/ with pskoett/ everywhere it is used as a git URL or
  GitHub link.
• Either rename clawdhub → openclaw / clawhub in install commands, or
  document clawdhub as a deliberate alias and clarify when it applies.

Context

• Installed via the published ClawHub package (SKILL.md frontmatter: v4.0.0).
• Set up on Ubuntu 24.04, OpenClaw 2026.6.11.
• Verified against the ClawHub skill page and the local installed SKILL.md —
  both contain the same typos.
